Tesla is probably overvalued, but it's also not as simple as Tesla == cars. They're also one of the leading players in grid level battery storage (a market that will be huge soon). I don't think any other auto manufacturer is

Those people are sharing their screen using the features provided by Zoom etc, rather than sending screen data through a virtual webcam. The data is likely being treated differently by the videoconferencing system.

Your comment falls for the same trap the parent describes. London has loads of #2 style dance focused club nights which aren't usually particulary touristy (unless they're famous - eg ministry of sound, maybe fabric) and basically

The full article ( https://www.nytimes.com/2020/11/10/upshot/covid-testing-doct... ) suggests that this doctor alone has run 60,000 covid tests. Billing $2k a pop. That's $120 million (ok, maybe r

If it makes you feel any better, I'm in the same boat. I think I made about $100 profit from the 8 or so bitcoin I owned a decade ago. But I also know that even if I'd made double that, I'd never have had the nerve to hold fo

That money isn't being thrown into the sea though - it's being paid to all sorts of salvage companies, offshore specialists etc. It's not like the government will suddenly have 24bn less than they would otherwise.

A while ago I spent far too long trying to work out if carbon sequestration through wood (charcoal, in this case) was feasible. The answer is, partly. We probably couldn't fix global warming, but we probably could negate a reasonable c

It's mad that our screens had this fundamental widescreen shift and none of the user interface people changed anything. I've been moving my taskbar to the side of the screen for years - it just makes so much more sense on a screen

Wow! So the bulk of the energy we consume comes not from the hydrocarbons we're digging up, but the oxygen bonds we're breaking when we burn them. That's completely spun around my understanding of fuels. Fascinating. That als

Certainly that's true (although when I got an induction stove i only had to replace one pan - they've been widespread for long enough now that all the cookware I bought in the last decade is compatible, as are all my ancient cast

AWS can really sting you. I've completely stopped using it for private projects after receiving a $100 bill for something I accidentally provisioned through the command line. Not only is it very easy to spend real money by accident, th

Many people don't have a computer. Their smart phone is also their computer. There's myriad services in modern western life which require a computer of some sort to access. Increasingly government services, banks, transport, event

I hate it so much when I want to do some obscure thing on Windows, but when I go to the place you used to be able to do it, it's gone! Replaced with a "modern" control panel which doesn't support that obscure thing. Inst

It's a microcontroller rather than an application chip - so the amount of RAM will always be significantly less. A really beefy high end microcontroller might have 1MB of internal RAM - and for most applications that's more than e

Car infotainment systems run ARM SoCs, much like an iPhone. To compare the complexity of a car and a phone (any modern phone - they're all fundamentally similar inside) belies immense ignorance of both. Phones are functionally complex,

Yes, completely sure. Corner reflectors are used to calibrate SARs by providing fixed bright ground points. I've also seen SAR imagery where unintentional corner reflectors (in this case, a building) completely washed out the image at

by leoedin 6y ago
If you want to block SAR, just set up a big corner reflector near you. It'll completely blind the part of the image near you. It would also draw a lot of attention to you... So maybe not the best approach if you're trying to hide.

Power usage isn't necessarily huge. I worked on a SAR satellite a few years ago with a total RF power of <1kW. It's pulsed as well - you send an RF "chirp" at a sub-1kHz pulse frequency. Depending on imaging mode the

Would you say you're most alert in the morning or the evening? I've always found myself alert and energised in the evening, and sluggish and unalert for the first few hours after waking. I'd be very surprised if my productivi

Hospitalised cases lag infections by weeks. For some reason you're completely ignoring the positive test results, which show a very clear correlation with lockdowns. https://www.theguardian.com/world/2020/dec&

To be clear, the UK entered a lockdown excluding schools on the 5th of November. Within a week, positive tests started declining significantly. The lockdown ended on the 2nd of December. Within a week, positive tests started going up again.

4K is 4x the pixels of standard HD. You can fit 4 HD windows next to each other. That's a huge difference! Any work with spreadsheets or multiple window code comparison benefits tremendously.

The scale of the required liquidity of the energy market is growing constantly. Every time a solar panel or wind turbine is installed, the need for variable power sources goes up. If we're going to go anywhere near the net zero target

Pyrolysis of trees can produce charcoal (biochar) which is stable in soil for thousands of years (and potentially stable in other locations for much longer). I wonder if you could pyrolyse mushrooms to produce similar products.

This isn't really discussed enough. There's so much chemical energy in plastic that it really is just a matter of time (although evolution scale time could be thousands to millions of years...) until something evolves to break it
